Question

According to the ideal gas law, what is the approximate volume that will be occupied by $0.5mole$ of an ideal gas at ${30}^{o}C$ and $3atm$ pressure (gas constant $R=0.0821L.atm/(mol.K)$)?

• A. Less than $1L$
• B. $5$ $L$
• C. $10$ $L$
• D. $15$ $L$

Answer 1

Answer: (B)

$5$ $L$

$n=0.5T=30℃=303KP=3atmV=\frac{nRT}{P}=\frac{0.5\times 0.0821\times 303}{3}=4.14L$

which is most close to 5L

Ans: 5L
